EL5325

® EL5325 Data Sheet March 5, 2004 FN7437.1 12-Channel TFT-LCD Reference Voltage Generator The EL5325 is designed to produce the reference voltages required in TFT-LCD applications. Each output is programmed to the required voltage with 10 bits of resolution. Reference pins determine the high and low voltages of the output range, which are capable of swinging to either supply rail. Programming of each output is performed using the 3-wire, SPI compatible interface. A number of EL5325 can be stacked for applications requiring more than 12 outputs. The reference inputs can be tied to the rails, enabling each part to output the full voltage range, or alternatively, they can be connected to external resistors to split the output range and enable finer resolutions of the outputs. The EL5325 has 12 outputs and is available in a 28-pin TSSOP package. They are specified for operation over the full -40°C to +85°C temperature range.
